USDC vs USDT — which stablecoin to pick in 2026

The two main stablecoins compared on reserves, transparency, liquidity, and depeg risk. Where each makes sense.

Depeg history: dropped to $0.95 in 2022 after the Terra/Luna collapse. Recovered in days.

USDC (Circle)

Issuer: Circle (US)
Market cap: ~$45B+
Reserves: cash + short-term US Treasuries
